Answer:
(Choice A) 5M
Step-by-step explanation:
Let total no. of e-mails in inbox be x
Since she read 80 % of mails i.e 80 % of x
⇒
⇒
⇒
So, she read 0.8x e-mails.
So, remaining email = total e-mails - read e-mails
Since we are given that Danette still has M unread e-mails.
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Thus the expression represent the number of e-mails Danette had in her inbox before she started reading is 5M.
Hence Choice A is correct.
1st one is 0
2nd one is -3
3rd one is -2
4th one is 5
Combine like terms, isolate the variable, and make the slope of the variable 1 to find all the answers.
The answer is the sum of three times a number and six, divided by the difference of seven times a number and nine.
The phrase is(3p+6)/(7p-9)
Let’s describe each factor:
3p is three times a number
7p is seven times a number
3p+6 is the sum of three times a number and six
7p-9 is the difference of seven times the number and nine
The last two factors are divided, so
(3p+6)/(7p-9) is the sum of three times a number and six, divided by the difference of seven times the number and nine.
I hope this helped and have a nice day!
Answer:
Chlorine: -34 °C
Krypton: -153.2 °C
Step-by-step explanation:
Boiling point of elements in degree Celsius (°C)
Argon: -185.8 °C
Chlorine: -34 °C
Fluorine: -188.1 °C
Hydrogen: -252.87 °C
Krypton: -153.2 °C
Helium: -268.9 °C
Boiling points that are above the boiling point of Argon.
Chlorine: -34 °C
Krypton: -153.2 °C
